This invention relates to agricultural ma blocking cultivator;

The'primary ob ect of'the' present inventionis to prov-ideacottonblocking cultivator" .w thfwhich fourirows of cotton} or other;

pla ts'rna'y 'loe cultivated at a tirne to remove I I a certainnuinberofthe young plants quickly, v r p and efficiently aridTWithohtdisturbing the 5 plants which aretobesaved." i

A further objeet iofth e invention is tojpro; an of vide a machineemploying rotating hoes wherein the gangs maybe adjusted to differentanglesandwherein'thefhoes ofea'ch:

3 "i5 ganglmay beindividuallyadjusted as] dc? lr d- Still anotherobject'of the invention to provide a cultivator remploying rotating I igangsof hoeseach of which'ga ngs may be so arrangedas to rotate inaplane disposed at the most advantageous angle to the ground,

" A still further obj ect ofthein vention is to angs ofihoes provide acultivator'ernploying I p wherein all of the gangs maybe shiftedvertically as desiredand wherein also certainoscill'at'ory" movement 01the gangsis ermitted for adjustment."

Each of the clamps 20 secures riphery of the wheel the shank ofa' hoe19, the lower end .or blade of which may be straight or turned to extendat an angle as, shown. It will be readily seen that by loosen ing theclamps 19' the hoes may be adjusted vert-icallytoarrangethem in aposition best suited for the conditions under which the machine isto beused:v r

For the support and conveyance of the cultivator structure over theground there is provided a carriage consisting of an inverted U-shapedaxle beam 28 the central portion of wheel 3a.

to the 'perei'itending forwardly therefrom an arm to lends :1 dependingeye 37..

which .issecured to a center beam 29 the iorward end of whlch isdesigned to overhe the draftbeam 3.

The connection between i the forward end of the beam 29 and the draftbeam 3 is preferably pivotal as indicated at '30 so that the rearportion of the cultivator structure may be lii'tedjwhen desired toremove the gangs from contact withthe ground. The rear portion of thebeam 29 may be employed for the supportofan operators' seat 31'.

Pivotally attached to each depending portion32 o theaxle 28 is aVertical axle 33 upon the lower end of which is mounted a Each of thevertlcal axles 33 has yvhichisattached one end of a link 36 which runstoward the center of the machine.

,Mounted in; suitable supporting guides 36 upon the underside of thebeam 29 is a transversely extending reciprocable plate or bar to eachend of which an end of a link36 is attached. 'This bar has intermediateits .lllountedat each-end of a cross beam 38a is pulley wheel 386, overeach, of which runs a chain 3 8c one end ofiea ch chain being attachedtothe eye 37 as shown in Figure 8;

, Pivotally mounted beneath the bar 29 are toot levers 38 each.of,wl1ich has theother end of a chain attached thereto. lVith theconstructionjust described it will be seen that by applyingpressure'tofone or theother or" th footlevers 38 the varms 35 of theaxles 33 may be swung in a desired direction for guiding the mach ne. rv

Secured to thebeam 29 isa pair of spaced depend ng gu de arms 39wh1chextend downwardlylon oppositesides of the beam 3.

Mounted to extend transversely of the brace arms Owhich connect theforward part ofrtheibeam29 the outer portions of the axlestructureQS isan oscillatory shaft ll carryinga control lever42 which is pivotallymounted above the Sl1lft upon a toothed segment 43 thelevercarrying theusual spring controlled latch member for engagement with this segment tomaintain the shaft in any desired position. Theouter ends of theshaftllare turned to provide or-v wardly extending arms i l the free end ofeach of which is connected by a depending link a5; with an underlyingportion of the frame 1. It will thus'be seen that-by oscillating thelever 42 the arms l will be raised or lowered to bring the beams 3 and29 into substantially parallel relation to lift the gan s of hoes 2Ofromcontact with the ground.

, In order to adaptthe present machine to use with a tractor thereisp'rovided a frame structure such as is illustrated in Figure (3 whichframe consists o ffront and rear transverse beamsdG and/l7, the beambeing bolted acrossthe frontportlon of the trac- I connected at oneendto an endof the for- I pair of stub axles suspendedfrom the endsconnecting-with the connected at'one'endto an end of ward one of thefirst mentioned beams, an osarm having connection side bea'myan axleextending transverselyof vried by each a stub axle,

of each of said axles, a wheelcarried by each stub axle, earth workingelements secured to axle; and rotatable thereabout, an arm connected'atone-end with eachstubaxle, and

means for connecting the other end of each arm with the adjacent beam,said adjustable connection facilitating the holding of the stub axle inan adjusted position to which it may be swung upon its tpivot.
